With MapServer, you can do that with a bit of client side bounds creation, and a WFS query: the boston freemap does this (though it did it *long* before vector layer, so it's only used to display attributes): http://boston.freemap.in/ lets you click on the map, and yo'll see a list of streets near your click on the right hand side. The geometry is there in the response: you could easily toss the URL directly into a Layer.GML and just add that to the map, rather than doing anything more complex. Gregor: Would you be willing to combine these suggestions into a wikipage on the OpenLayers wiki? I think that it's a generally useful question, and this thread has covered a lot of good ideas.
